In my opinion they are nowhere near the best books written on racing. If you want to become a successful punter I can recommend at least 5 books you should be before hand...but I digress.

I'm not bagging the books, I have two or maybe three. It depends what you are into and what stage of your punting journey you are at. They focus heavily on finding the answers to racing through statistics, relative frequencies for different form factors...all statistically and mathematically based. One book has a minor chapter on Speed Ratings, which is more of an broad overview to how is Tasmanian Business Speed Handicapping Services goes about their work...again very mathematical.

You won't find anything in them to develop essential knowledge and skills to be a successful form analyst and bettor i.e. class, distance, fitness, form, pace, betting habits etc but if you are statistically inclined, believe they can actually make you winner and / or are interested in exploring that side of racing then you should definitely get a hold of them.
